Are neuronal intranuclear inclusions the common neuropathology of triplet-repeat disorders with polyglutamine-repeat expansions?
Neuronal intranuclear inclusions have been found in the brain of a transgenic mouse model of Huntington's disease and in necropsy brain tissue of patients with Huntington's disease. We suggest that neuronal intranuclear inclusions are the common neuropathology for all inherited diseases caused by expansion of polyglutamine repeats. We also suggest that patients with a pathological diagnosis of ...

متن کاملMolecular Models for Repeat Expansions
Expansions of simple DNA repeats account for more than two dozen hereditary disorders in humans (for recent reviews see Lenzmeier and Freudenreich, Jin and Warren, Parniewski and Staczek, Ranum and Day, Brown and Brown, Cummings and Zoghbi, Bowater and Wells, and Siyanova and Mirkin). Table 1 describes those diseases and their important genetic features. Although originally discovered expansion...
متن کاملExpression characteristics of triplet repeat-containing RNAs and triplet repeat-interacting proteins in human tissues.
Numerous human transcripts contain tandem repeats of trinucleotide motifs, the function of which remains unknown. In this study we used the available gene expression EST data to characterize the abundance of a large group of these transcripts in different tissues and determine the mRNAs which had the highest contribution to the observed levels of transcripts containing different types of the CN...
متن کاملThe 26S proteasome drives trinucleotide repeat expansions
Trinucleotide repeat (TNR) expansion is the causative mutation for at least 17 inherited neurological diseases. An important question in the field is which proteins drive the expansion process. This study reports that the multi-functional protein Sem1 is a novel driver of TNR expansions in budding yeast. Mutants of SEM1 suppress up to 90% of expansions. Subsequent analysis showed that Sem1 faci...
